In recent decades, the number of rainfall-induced landslides has increased significantly in many parts Malaysia, especially urbanized and hilly areas. The disturbance morphology as a result human activities potential for erosion on man-made slopes, during extreme rainfall rain events. Most areas Malaysia are covered by thick layer soil, which is known to have significant impact soil erosion. Ho...

introduction rainfall erosivity, the propulsion or power of causing erosion in separation and transport of soil particles, is in relation to water erosion. rainfall erosion is causing loss of soil, damage to agriculture and infrastructures which is followed by water pollution. changes in rainfall patterns exacerbate risk of erosion globally. rainfall erosivity plays an effective role in soil er...

Biancana badlands are peculiar landforms in the Basilicata region of Italy resulting from local combination geological, geomorphological, and climatic settings. The evolution mainly depends on slope erosion, which is controlled by angle, exposure, vegetation its interactions with insolation, rain, wind. Multi-temporal, detailed, high-resolution surveys have led researchers to assess changes slo...

A methodology was developed to estimate quantities of crop residues that can be removed while maintaining rain or wind erosion at less than or equal to the tolerable soil-loss level. Six corn and wheat rotations in the 10 largest corn-producing states were analyzed. Residue removal rates for each rotation were evaluated for conventional, mulch/reduced, and no-till field operations. The analyses...

This paper proposes a paradigm shift in the numerical simulation approach to predict rain erosion damage on wind turbine blades, given blade geometry, its coating material, and atmospheric conditions (wind rain) expected at installation site. Contrary what has been done so far, simulations (flow field particle tracking) are used not study specific operating condition but build large database of...

A2Dvideo disdrometer (2DVD) probewas used to gather detailed dropmeasurements over a 770-min rain event. Accumulated totals of the rainfall and of the number of drops for each square centimeter showed persistent, significant correlated structures across the approximately 11 cm3 11 cm grid of the 2DVD. This is surprising because larger-scale studies suggest that the values in each square centime...

UNLABELLED Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. OBJECTIVE This review discusses the role of salivary factors on the development of dental erosion. MATERIAL...

Rain erosion on the leading edge of wind turbine blades is an intricate engineering challenge for industry. Based energetic approach, this work proposes a methodology to characterise capacity raindrop impacts onto blades. This can be used with meteorological data from public institutions or direct measurements at locations. The characterisation analysed using accumulative and per impact erosive...
